--- Comment #1 from Fujii Hironori <Hironori.Fujii at sony.com> ---
Running a single DRT/WTR is stable, no flaky failures.

> python.exe ./Tools/Scripts/run-webkit-tests --wincairo --release --no-retry-failures --iterations=10000 --exit-after-n-failures=20 --no-show-results http/tests/css/border-image-loading.html

However, running multiple curl commands in the background to stress the httpd makes the WTR fail.

> seq 10000 | xargs -n 1 -P 16 curl -s http://127.0.0.1:8000/css/border-image-loading.html -o

In this case, all generated curl output files are exactly same. I think this is not an Apache bug.
